Space type
|
Used to set the default type of conditioning used to
maintain the room design temperatures for rooms of the selected room type.
Available Space types appear on the drop-down list:
-
Ventilated — Defines the room space as having only ventilation. This can be
natural ventilation or mechanical ventilation or a combination of both. Energy
usage is considered for the fan equipment used in ventilating the room
-
Unconditioned — Defines the room space as having no air conditioning. Meaning
there is no HVAC equipment servicing the room, which affects simulations and
energy calculation results.
-
Semi-heated — Defines the room as being a semi-heated space. Typically,
semi-heated spaces are large warehouses where a minimum temperature is
maintained to allow for adequate working conditions.
-
Residential conditioned — Defines the room as being a conditioned residential
space. Conditioned residential spaces in buildings are used primarily for
living and sleeping. Residential spaces include, but are not limited to,
dwelling units, hotel/motel guest rooms, dormitories, nursing homes, patient
rooms in hospitals, lodging houses, fraternity/sorority houses, hostels,
prisons, and fire stations.
-
Non-residential conditioned — Defines the room as being a non-residential
conditioned space. Non-residential conditioned spaces are building areas that
are not used for living or sleeping.

Thermal weight
|
Used to set the Thermal weight factor used for
rooms of the selected room type. The thermal weight of a room refers to the
extent of the room's energy consumption occurs with changes in local weather
conditions.
- Light
— Sets the room to have a light thermal weight. Thermally light rooms are those
whose heating and cooling requirements are proportional to the weather.
- Medium
— Sets the room to have a medium thermal weight. Medium weighted rooms have
heating and cooling requirements that are proportional to the weather to a
lesser degree than lightly weighted rooms. They require more energy to
condition them than thermally light rooms, and less energy than thermally heavy
rooms.
- Heavy
— Sets the room to have a heavy thermal weight. Thermally heavy rooms have
heating and cooling requirements that are not proportional to the weather.
Heavier rooms being less dependent on weather than lighter rooms, are less
likely to produce accurate results in simple temperature dependent energy
consumption calculations.

Furniture amount
|
Used to set a default Furniture amount factor to be
used for rooms of the selected room type. The amount of furniture in a room
affects the amount of thermal energy the room gains or loses. Furnishings
create additional surface areas which affect thermal gains and losses.
Furniture also covers floor and wall areas, providing an insulating effect in
the room space
- Low —
Sets the room to have a low amount of furniture.
-
Average — Sets the room to have an average amount of furniture.
- High —
Sets the room to have a high amount of furniture.

Furniture weight
|
Used to set a default Furniture weight factor to be
used for rooms of the selected room type. Furniture weight in a room refers to
the amount of weight per unit of floor space furniture exerts. This factor
affects the amount of thermal energy the room gains or loses.
- Light
— Sets the room to have a light furniture weight factor. Low mass furniture
absorbs and emits less thermal energy at a faster rate than more massive
furniture.
- Medium
— Sets the room to have a medium furniture weight factor. Medium mass furniture
absorbs and emits thermal energy at a slower rate than less massive furniture,
but faster than more massive furniture.
- Heavy —
Sets the room to have a heavy furniture weight factor. High mass furniture
absorbs and emits more thermal energy but at a slower rate than less massive
furniture.
